 For example, if you select the 20,000 RU/s max throughput option and have 200 GB of storage with four physical partitions, each physical partition can be autoscaled up to 5000 RU/s. If there was a hot partition on a particular logical partition key, you'll see 429 responses when the underlying physical partition it resides in exceeds 5000 RU/s, that is, exceeds 100% normalized utilization.

 Another common question that arises is, **Why is normalized RU consumption 100%, but autoscale didn't scale to the max RU/s?**
